Will Heron’s formula produce the same results as the area of a triangle formula that you have already learned? Create a WORD problem that can be solved by using BOTH Heron’s formula AND A=bh. Solve the problem using both formulas and discuss your results. HINT: Try drawing a triangle first and then measure the lengths of the sides.

In a right triangle, the side opposite the right triangle is called the hypotenuse and plays a different role in the formulas than the other two sides. But in a general triangle, all the sides are interchangeable in the formulas. That’s very easy to see and use in the Law of Sines, but takes more thought in the Law of Cosines.
